Title: Method of joining metallic members and method of reflow soldering
Inventor: MORO TAKASHI
IPC: B23K11/24
Filed: 2000-03-22
Abstract: PROBLEM TO BE SOLVED: To immediately break the supply of a normal electric current even in the halfway time of an AC wave when such a situation happens that the supply of a normal electric current should be interrupted before the termination of a predetermined time of supplying the electric current in a joining or a reflow-soldering of metallic members where an electric current having an AC wave form is used. SOLUTION: A controlling part 32 operates a continuous switching at an inverter frequency only for switching elements (22 and 26) on the positive pole side while keeping switching elements (24 and 28) on the negative pole side off at every unit energizing period of an odd number among plural unit energizing periods which compose a set energizing time, and operates a continuous switching at the inverter frequency only for the switching elements (24 and 28) on the negative pole side while keeping the switching elements (22 and 26) on the positive pole side off at every unit energizing period of an even number.  Thus, a secondary electric current 12 having the current form of a near trapezium flows in the secondary circuit of a power supply unit, in the positive pole direction in every unit energizing period of an odd number, and in the negative pole direction in every unit energizing period of an even number. When a breaking signal WS of the electric current is inputted during the time of the normal energizing, the controlling part 32 interrupts the switching control of an inverter 16 and immediately stops the supply of the normal electric current.

Title: Fuel pressure control device for internal combustion engine
Inventor: DEMURA TAKAYUKI
IPC: F02M59/20
Filed: 2000-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a fuel pressure control device for an internal combustion engine capable of suppressing an excessive rise in actual fuel pressure beyond a target value according to erroneously excessive increase in an integration term when the fuel discharge amount of a fuel pump is a value in the vicinity of a maximum value. SOLUTION: Fuel pressure within a delivery pipe 53 is controlled by controlling fuel discharge amount of a high pressure fuel pump 47 based on a duty ratio DT calculated from an integration item DTi. The integration item DTi is updated based on a difference of actual fuel pressure P and target fuel pressure P0. The integration item DTi is gradually updated toward a side (increase side) in which the integration item DTi increases fuel discharge amount of the high pressure fuel pump 47 under the circumstances that it takes time to raise actual fuel pressure P up to the target fuel pressure P0. But when fuel discharge amount of the high pressure fuel pump 47 becomes a value in the vicinity of the maximum value, the update of the integration item DTi is inhibited and excessively increasing side value of the integration item DTi is avoided.

Filed: 2000-03-21
Abstract: PROBLEM TO BE SOLVED: To easily execute data rewrite at high speed irrespective of data from an external device by rewriting data in a memory call while using a write signal generated by a signal generating means in a memory device. SOLUTION: In a control circuit 1, read data DO are controlled/corrected by external data X and Y and written in a memory cell 2. When this control operation is illustrated, a mode I is a mode defining the external data Y as write data Z and a mode II is a mode defining the read data DO as write data Z. Thus, two modes for correcting/writing the read data DO in the memory cell 2 (mode II) and for writing external data Y (mode I) can be controlled by the external data X and Y under control from the outside. Concerning the control, the modes I or II is designated by the external data X and the non- inversion/inversion of the read data DO in the mode II is designated (corrected) by the external data Y.
